College Physics - Research Paper Example According to the electromagnetic theory, a charged particle in accelerated motion must radiate energy in the form of electromagnetic radiation. So an electron revolving around the nucleus must also radiate energy and finally fall into the nucleus following a spiral path. 5. Although these quarks can not be isolated individually, but in combination with the others it can give existence to subatomic particles as electrons and protons. An electron is made up of one up-quark and two down-quarks (u, d, d) and a proton is made up of two up-quarks and one down-quark (u, u, d). Water or moisture on the earth absorbs heat from the sun and the surroundings. When enough heat has been absorbed, some of the liquid molecules have enough energy to escape from the liquid and begin to rise into the atmosphere as a vapor. As the vapor rises higher, the temperature of the surrounding air becomes lower. Eventually, the vapor loses enough heat to the surrounding air to allow it to turn back into a liquid. Earth's gravitational pull then causes the liquid to "fall" back down to the earth, thereby completing the cycle. It should be noted that if the temperatures in the surrounding air are low enough, the vapor can condense and then freeze into snow or sleet. Once again, gravity will claim the frozen forms and they will return to the earth. Like giant capacitors in the sky, these clouds get charged up. The upper portion of the cloud is positive
